Roy and HG are an Australian comedy duo, comprising Greig Pickhaver in the role of "H. G. Nelson" and John Doyle as "'Rampaging' Roy Slaven". Their act is an affectionate but irreverent parody of Australia's obsession with sport. Their characters are based on stereotypes in sports journalism: Nelson the excitable announcer, and Slaven the retired sportsman turned expert commentator. In his 1996 book Petrol, Bait, Ammo & Ice, Pickhaver summarised the duo's comedic style as "making the serious trivial and the trivial serious".

The duo's long-running triple j radio program This Sporting Life was added to the National Film and Sound Archive's Sounds of Australia registry in 2013, and the This Sporting Life 30th anniversary retrospective collection won the ARIA Award for Best Comedy Release in 2016.

Since March 2020, Roy and HG's weekly show Bludging on the Blindside airs on Saturday afternoons on ABC Sport, ABC Local Radio, and the ABC Listen app, as well as podcast platforms.

It was reported in July 2021 that Roy & HG would host Dodging Armageddon, a daily podcast for ABC Radio with an Olympics theme, which will air throughout the XXXII Olympiad's competitions.
